This functional student desk chair is a great addition to any classroom or home. Highlights include a clear, removable bin (a proven customer favorite in our mobile bin storage units) that provides a roomy place to store papers, pencils, and other small items. Four casters (each with a locking brake) and a built-in grab handle make the chair easy to move across a variety of surfaces then stacked up to three high for space savings and easy storage. The school chair is also perfectly sized for young learners and - thanks to a sturdy plastic seat and all-metal frame - is easy to clean. Removable, clear 3"- deep MBS storage bin with a 20 lb. weight capacity. A clear plastic bin lets you know the contents at a glance. Built-in safety feature prevents the bin from accidentally being pulled off its track. Full-swivel, lockable casters for easy mobility. Caster locks secure both the wheel and the swivel mechanism. Child-safe air vent on backrest keeps students cool. Built-in grab handle. Durable plastic construction is easy to clean. Sturdy steel frame with white powder coat paint finish. Easy, tool-free assembly. Casters: full-swivel (each with a locking brake that secures both the wheel and the swivel mechanism). Recommended maximum stack height: 4 chairs.
